Title: Simulation of LNA+MIXER in SpectreRF simulat
Post by mahbub Reja on Feb 11^th, 2004, 3:42pm

Hi all,

How, can I simulate LNA+Mixer together with SpetreRF simulator?

I want to do simulation for conversion gain, noise-figure, 1dB compression point and IP3. What analyses, I should do. Before I simulate only mixer with PSS, Pnoise, PSP and PAC and I had three ports (RF input, LO input and IF output ports) . I am wondering, How can LNA and mixer be combinedly simulated. Suppose, I want to do in this way that I set RF input as LNA input, IF output as Mixer output and third port as LO input of mixer. If I simulate now for conversion gain with PSS and PXF, will it work or not?

Please, Someone help me with simulation setup for LNA and Mixer together. Please Tell me the links, Where I can get documentations for simulation setups for LNA+MIXER.

Best Regards

Mahbub,
One simulates the combination of an LNA and mixer in exactly the same way as one simulates a mixer alone. Rather than driving the input of the mixer, you drive the input of the LNA and let it drive the mixer.
